|We know that at series resonance inductive reactance = capacitive reactance. Therefore total impedance is only the net resistance of the circuit. Here the net resistance is = (120+12) =132 ohm.
So, current at the resonant condition = 12V/132 ohm = 0.09A.
As the output voltage is taken off the resistor, so the output voltage at center frequency is = (0.09*120) = 10.9V.

|But your solution doesn't account for the center frequency equation.|

|Center frequency means critical frequency and it is calculated on the basis of critical frequency.|
